Abstract

Kinetics of oxidation of methyl glycol (MG) and diacetone alcohol (DAA) by periodate in the presence of ruthenium(III) chloride as homogeneous catalyst have been studied in acidic medium. The results indicate zero order dependence of the reaction on [IO4-] while first order kinetics with respect to [Ru(III)] was observed. First order in both [MG] and [DAA] was observed while positive effect of [H+] was exhibited. Variation of ionic strength of the medium and addition of potassium chloride did not bring about any significant change in the rate of the reaction. Showing thus zero effect of ionic strength and added chloride ions. A suitable mechanism consistent with kinetic results has been proposed and rate law has been deduced for the title reactions.
